Import align CelebA dataset

A Datumaro project with an align CelebA source can be created in the following way:

datum project create
datum project import --format align_celeba <path/to/dataset>

It is also possible to import the dataset using Python API:

import datumaro as dm

align_celeba_dataset = dm.Dataset.import_from('<path/to/dataset>', 'align_celeba')

Align CelebA dataset directory should have the following structure:

dataset/
├── dataset_meta.json # a list of non-format labels (optional)
├── Anno/
│   ├── identity_CelebA.txt
│   ├── list_attr_celeba.txt
│   └── list_landmarks_align_celeba.txt
├── Eval/
│   └── list_eval_partition.txt
└── Img/
    └── img_align_celeba/
        ├── 000001.jpg
        ├── 000002.jpg
        └── ...

The identity_CelebA.txt file contains labels (required). The list_attr_celeba.txt, list_landmarks_align_celeba.txt, list_eval_partition.txt files contain attributes, bounding boxes, landmarks and subsets respectively (optional).

The original CelebA dataset stores images in a .7z archive. The archive needs to be unpacked before importing.

To add custom classes, you can use dataset_meta.json.

Export to other formats

Datumaro can convert an align CelebA dataset into any other format Datumaro supports. To get the expected result, convert the dataset to a format that supports labels or landmarks.

There are several ways to convert an align CelebA dataset to other dataset formats using CLI:

datum project create
datum project import -f align_celeba <path/to/dataset>
datum project export -f imagenet_txt -o ./save_dir -- --save-media

or

datum convert -if align_celeba -i <path/to/dataset> \
    -f imagenet_txt -o <output/dir> -- --save-media

Or, using Python API:

import datumaro as dm

dataset = dm.Dataset.import_from('<path/to/dataset>', 'align_celeba')
dataset.export('save_dir', 'voc')

Examples

Examples of using this format from the code can be found in the format tests
